(b) DESCRIPTION OF THE PRIOR ART

To improve heat exchange performance of a movable air conditioningdevice, circulative re-use of water condensed in the air conditioningdevice is a feasible solution. Heretofore, a movable air conditioningdevice uses the condensed water in either one of the following ways. Thefirst way of using the condensed water is to use a water pump that isarranged in a water collection tray to pump water to a condenser forre-use of the water. The second way is to use a shaded pole electricmachine to drive vane wheel for spread water as droplets that aresprayed over a condenser so as to realize the re-use of the condensedwater. Both arrangements of re-use of condensed water are effective inimproving heat exchange performance of the movable air conditioningdevice. However, the costs of re-using condensed water with these waysare high and the waste of resources is severe.

The water pumping device comprises a cylinder 29,and the cylinder 29 forms therein a water inlet chamber 30, a wateroutlet chamber 31, and a piston chamber 32. The piston chamber 32 isdefined by an upper piston retention board 6 and a lower pistonretention board 7. The piston chamber 32 receives therein a piston 5,which is coupled to the transmission mechanism. The water inlet chamber30 and the piston chamber 32 communicate each other through a waterinlet piston 9, while the water outlet chamber 31 and the piston chamber32 communicate each other through a water outlet piston 12. The waterinlet chamber 30 comprises a water inlet port 8, which communicates thewater collection tray 18 through a water inlet pipe 14. The water inletchamber 30 is sealed by a water inlet chamber plug 10 and the wateroutlet chamber 31 is sealed by a water outlet chamber plug 11.

When the piston 5reaches a highest position, water contained in the water collection tray18 that is located at the bottom is conveyed through the water inletpipe 14, the water inlet port 8, and the water inlet piston 9 to flowinto the cylinder. When the piston 5 reaches a lowest position, thewater received in the cylinder moves through the water outlet piston 12,the water outlet port 13, and the water outlet pipe 15 to reach thewater spraying tray 16 from which the water is sent to a condenser toincrease the heat exchange rate of the air conditioning device. In thecourse of the operation of the electric machine, this process iscyclically repeated.

The connection rod 4 has an end coupled to a piston 5.

The operation of the third embodiment is as follows. The synchronouselectric machine 28 drives the crank 2 and the connection rod 4 toproduce reciprocal movement of the piston 5. When the piston 5 reaches ahighest position, water contained in a water collection tray 18 that islocated at the bottom is conveyed through a water inlet pipe 14, a waterinlet port 8, and a water inlet piston 9 to flow into a cylinder. Whenthe piston 5 reaches a lowest position, the water received in thecylinder moves through a water outlet piston 12, a water outlet port 13,and a water outlet pipe 15 to reach a water spraying tray 16 from whichthe water is sent to a condenser 17 to increase the heat exchange rateof the air conditioning device.
